Fire in the hole is a long-running warning call in shooter games, shouted when a grenade or explosive is about to go off. In Garry's Mod, that call took on a second life through Nextbot memes, where unstoppable chasing characters and loud, distorted edits turned ordinary gameplay into short, shareable horror-comedy clips. Those videos spread widely on TikTok and YouTube, where the phrase became shorthand for impending chaos. It is still used because the warning is instantly understood, even by viewers who have never played the game.
